IMPROVEMENTl@ CHURNS.

Speciiication forming part of Letters Patent NO. fl., dated May l, 1866.

To all whom it may concern:

Be it known that I, StLAs Hnwrr, ot' the town of Seneca Falls, in Seneca county, State of New York, have invented a new and lmproved inode of Constructing Ghurns; and l'. do hereby decla-re the following to be a full, clear, and exact description of the same, reference being had to the accompanying` drawings, making a part of this specification, and to the letters ot' reference marked thereon.

.The object of this invention is to lessen the time and expense ordinarily incurred in making butter from cream; a'nd it consists in the following points: first, the gearing the two paddles together; second, the inode of tightening the bearings by means of a stufng-box; third, shifting the position ofthe driving-wheel stud so as to cause it to engage another' wheel, and by this means reverse the direction ot' the paddles; fourth, the mode ot' constructing the paddles or dashers; fifth, the mode of grooving into wood the zinc bottom, sixtlnthe mode of conveying the water to the water-chamber5 seventh, the bridge under the zinc bottom for the purpose of supporting the same, eighth, raising the lid a small distance from the bottom ot' the rabbet in which itis placed by means ot' small pieces in the corners, for the purpose of additional ventilation, and to let the cream iiow freely back into the churn; ninth, the break or triangle-piece on the bottom of the churn, all of which I will proceed to describe,

Figure l is a perspective View or elevation of said churn. Fig. 2 is another perspective view thereof without the top, showing the gears and their relations to each other. Fig. 3 is a geometrical plan of one of the paddles or dashcrs and its immediate connections. Fig. et shows the stand of the driving-wheel and how the same is changed so as to reverse the directions of the paddles.

In Fig. l, A is the zine bottom, (shown Iin red dotted lines,) and is grooved into the sides of the frame-work, as shown at B, the distance of the flat horizontal portion (shown between the two rows of red dotted lines) on all the sides, and cemented in that position. U is a break, triangular in form, placed on the bottom ot' the churn for the purpose of changing the direction of the currentand elevating it, so that it will come in contact with the dash on the opposite side. D is a hole for letting out the buttermilk. vE is a tube, used for the purpose of charging the water-chamber F with warm water in any case when that may be required to facilitate the operation ot' churning. Said chamber occupies the space immediately beneath the zincand main bottom ofthe churn, and the side pipe, G, opens into the same.

The top il has two air-tubes, l and J, opening into the churn, for the purpose of allowing the air to circulate freely among the cream while in the process of' churning. rihe top H rests at each ofthe t'onr corners on small pieces placed in the bottom ot' said rabbet, one of which is shown at R, Fig. 2.

in Fig, f5, L is the driving-wheel, having its bearings on the stud M. From the plane ofsaid wheel is projected a square stud, O. The two wheels P and Q, engage each other, and the wheel i" and the driving-wheel Lalso engage. The shaft ot' the wheel Q, extends from the tace of the said wheel, in form like the stud 0 in the wheel li. Onto either may be slipped a crank for operating the churn. The shafts ot' the two wheels O and F extend through the side of thechurn, as` shown in Fig. 3.

In Fig. 3, it is the woodwork of the side of the churn. S is the tlange-box secured to the side lt, one portion of which is inserted into the side, asshown at T. The hole allowing tlieportion T of the box S to enter the side is bored nearly through, and between the end of box S and the bottom of the hole is a space, U. This space is filled with cotton-waste or other librons material packed firmly in, so that no leakage-'of the cream from within can occur.

Those portions of the shafts F and Q projecting from the plane ofthe inside are made square, and the shaft V, on which the dash or paddle is constructed, has a socket., YV, fitted thereto.

The paddles X and Y are let into the center of the arms A B, and pins l 2 3 et put through both. Said arms are circular in form, and fit firmly into the holes bored for them in the shaft V, andare there secured in their proper places by means of the pins 6.

he stand Gf, Fig. el, from which project the bearings iwi from the driving-wheel L, is made adjustable, for the purpose of disengaging the two wheels ll? and L, and causing the wheels L and Q to en gage for the purpose of revers ing the direction of the paddles. This is aecomplislied by drawing the screws D and E', and moving the stand over until, without taking out die screws, the heads thereof will oeeupy the spaces F and Gr in said stand.

The bridge H is for the purpose of supporting the zine bottom, (shown partly in red dotted lines, Fig. 1.)

Having above described the construction and inode of operating my invention, what I claim as new, und Wish to secure by Letters Patent, is-

1. The beaters XY, in combination with the triangular break Gr, as and for the purpose specified.

2. The shifting-gear L, in combination with the gears I Q and beaters X Y, as and for the purpose specified.

3. The bridge H', for supporting the zinc bottom, as described.

4. The blocks K in euch corner, for the purpose set forth.
